Magnetism can be used to separate objects that are attracted by a magnet from objects that are not.
Solubility can be used to separate objects that dissolve in water from objects that do not.
Physical state can be used to separate objects that are solids from objects that are not.
A student classifies the objects shown based on their physical properties. Which property cannot be used to classify these objects into more than one group? (5.5A)

Two wires carrying electricity can create a spark if they come too close together. This spark can start a fire. Wires carrying electricity are usually covered with plastic to keep them from starting a fire. Why does the plastic keep the electricity from starting a fire? (5.5A)
Plastic is a good insulator.
Plastic can melt when heated.
Plastic is softer than wire.
Plastic conducts electricity.

For an investigation a teacher dropped a bolt into a container of maple syrup and asked students to remove it without touching the syrup.

A student measured out 10 mL of four clear liquids and added one drop of a different-colored dye to each liquid. One of the liquids was water. The student then carefully poured each liquid into a graduated cylinder and let the mixture settle for 30 minutes. The student observed that the liquids had separated into layers, as shown in the diagram. Which of these procedures would help the student identify the layer of water? (5.5A)
Stir the liquids, let them settle, and then identify the bottom layer as water
Drop a piece of ice into the graduated cylinder, let the ice settle, and then identify the layer just above the ice as water
Add water to the graduated cylinder, let the mixture settle, and then identify the layer that increases in volume as water
Carefully pour each layer into separate plastic containers, place the containers in a freezer, and then identify the liquid that takes the longest to freeze as water.
